Glad you're all finding this video useful! Quick note: We mainly focus on CAN BUS in this video but there are a number of network technologies other than CAN BUS that manufacturers have used. Some include FlexRay, LIN, heck GM was using J1850 VPW back in the C5 corvette. Still, you'd still need to build a translator from A to B, even if they use a different network technology.
seeing haltech gave me a warm and fuzzy feeling. as an aussie seeing haltech stuff used makes me happy because down here they are the goto for any engine swap or just tuning because modern ecus are like apple devices.
Chrysler had CCD or Chrysler Collision Detection. Confusing name, but it actually refers to the communication network and code to transmit messages without them colliding and garbling data.
You might be my favorite automotive youtuber ever. I am so sick, of seeing people talk about "ls swapping" everything, and never talking about having basic functions like this working again. Just get rid of power steering, ac, a functional gauge cluster, and throw in something aftermarket for rpms and call it a build. drives me nuts, contrary to common car guy belief, I dont actually want to drive a frame with an engine in it, I want to drive a car
Hahaha the opening of your video is the exact situation with our rotary swapped BRZ, Rotaru. Now, I did know this going into the project, but we accepted that not everything would work at first. We switched to a Link ECU from the ancient Apexi and it can interface with the CAN bus network. We knew Link had developed a BRZ stand alone, so we figured that would make life easy with the CAN decoding and transmitting. We didn't anticipate a few difficulties such as one out of two CAN networks being exposed. Basically we were already using one CAN connection for our CAN Lambda and CAN gauge, and you can't put the custom CAN and the OEM CAN on the same network. Also, despite Link now having all of the BRZ/86 CAN data available thanks to the plug in, it's not all publicly displayed since it's just used internally on a stock engine BRZ. This won't be a problem for many, but since we wanted to use the stock BRZ pedal for a DBW install, we were hoping to sniff accelerator pedal position data from the CAN network. We could overcome all of those issues with manual message reception instead of with the OEM CAN emulation, but then we'd need a hybrid CAN network. Like you talked about, you can define everything custom as long as you have message syntax. However, when we had the BRZ and aftermarket accessories on the same network, it seemed to cause some collision issues. So, we are adding a translator just to make our life simpler, though it could be fully done on the Link with a bit of board wiring and finding all of the correct CAN message syntax. Basically, we'll feed the translator RPM from the ECU and a few other basic signals to the translator and in turn we'll have a working dash, power steering, push to start, and more. We did find a workaround since the start of the swap where plugging in an OBD reader and turning the car on with a certain procedure enables most of the systems including power steering, but it's less than ideal. Also annoying to have to start the car with a switch and a big button, as much fun as the Clout Switch and Brap Brap Button are. Yes, let's definitely appreciate the people who take time to figure out all the CAN message info and share it publicly. A lot of people figure it out and keep it private either to have secret sauce or for profit. I'm not saying nobody deserves profit for their work, just sucks the car companies don't give it to us. Like you said, right to repair. One of the BRZ CAN experts is actually from Ukraine and has been participating in the war since it began. I messaged him on Facebook and luckily he is alright last I checked. Just wild how the car community can be linked like that. I hope he can go back to working on cars soon instead of fighting off an invasion. Lastly, I too love 80s/90s cars for simplicity, but obviously have to adapt. CAN is complex, but sharing information like this and everyone working together will only make it easier to deal with over time. There are certainly advantages along with the complexity. Let's keep making sick cars. Awesome video! Definitely going to help a lot of people understand. Subbed with the bell on.
Legendary comment tbh, and mirrors many of my own experiences. A rotary swapped BRZ sounds like a ton of fun! Been meaning to get my hands on a rotary myself but haven't found the time or money to do so just yet. If you happen to have the CAN message definition and are able to share (and haven't already), that'd be stellar! Thanks!
thank you for this!!!! I am about to start a pretty crazy swap project. I'm going stand-alone (haltech or link - not sure yet) but the car is vintage and want to use the factory interior switches from the 70's, use modern gauges with custom printed faces that mimic the originals. Your other videos are great too!
CAN was one thing then I learned about the existence of LIN, then working for Rover I heard of FlexRay; things are gonna get complicated. freaking power seats requiring a LIN wave form from the switch pack. Had an over head light that would come on by it self and was advised to send the LIN wave form. They don't even seem to know what their things are doing anymore.
I'm not a gambling man, but 100k in 2024 is in the bag. Content's all there, I think drop the green screen and replace static/zoom shots with lil vids and you'll up your game.
You do an amazing job explaining this stuff. I've learned more from your wiring related videos than I have my 14 years of school. Before I watched your engine wiring video this stuff was like an alien language to me. I currently have a 04 325ci sitting in my driveway and I'm thinking about putting an LS or SBC in it. Probably an SBC since this would be my 2nd time ever even pulling an engine but regardless carbureted or EFI my confidence on pulling the trigger on the swap has jumped. Plus your videos are purely entertaining as well.
Thank you Dave, and thank you BlackThumbTV. This is a very interesting subject and presented very well. P.s. your Head Gasket shirt almost got me in trouble at work, but instead "Karen" got told to chill the frig out. It was only visible on my way into the building unless she was undressing me with her eyes during work. 😅
Between you and I, I've personally developed something like this, however it can run independently on a Raspberry Pi as well as on mobile platforms. Just need the time/motivation to finish it and pop it in one of my cars. If you'd like to know more bug me in Discord, it's a pretty cool project!
7:56 I had to swap out my ECU for my '06 silverado bc it fried, but the one I got from the junkyard did not have any issues with the VATS it fired right up. Never knew the body control module did not allow the vehicle to start up if it detected another one.
Oh its the "broadcaster" now i finally understand... You must of been a teacher in your past life. Ty i get it know!🙏 ty dave... Haltech please just hire this guy
Really good video! I was excited to see Haltech coming out with the rebel LS but was disappointed to see it only has 1 dedicated Haltech bus. I am definitely going to go with a Haltech nexus R3 when I do my RX8 swap, the extra money is worth it for the seamless integration.
Been watching these vids bc ive considering swapping a v8 into my TJ. I saw that novak makes a "translator" that turns distributor pulses into crankshaft and camshaft signals the jeep ecu can use. Tempted to do this then literally take the check engine bulb out LMAO. Also bc im extra lazy, converting the tbi v8 into a carb to simplify things.
Love the video, you think you can make a video on k-line stuff? Like old Toyotas and Lexus have this and there’s such little info for someone to learn about it.
The secret to making people buy your product, "haltech" Make it simple and easy to use. haltech is pretty dope for allowing the translation on can bus, i dont know any others that does this.
Not only do the new electric Fords play fake engine noise, but everything that doesn't have a V8 does. I turned that feature off in my 3.5 l F150. What I don't understand is why it was ever there 😭 the natural engine sound makes plenty kf noise and sounds like a Nissan 370z from hell
Should can bus be legally standardized? Is there any proprietary tech involved that standardization would be harming some brands while helping others? Are there any reasons this would be any different from the obd port standardization? Love your content black thumb you definitely deserve more support than the algorithm is giving you 👍 ✌️
OBD hasn't aged well, imo. Manufacturers are adding new proprietary functionality to their cars that OBD simply isn't designed to work with. Things like reprogramming door control modules, or window modules, etc. The real answer would be to require manufacturers to document the protocols to do everything their magic little PDAs/softwares do, but that'll likely never happen
Can you make a video on your H6 UEL headers along with dimensions and which cylinders to pair? I got a 2011 3.7 v6 mustang that I love for the handling but I'm not a big fan of the VQ trumpet sound on a mustang
An LS RX-8 swap is exactly what I’m wanting to do. Does your swap have working ABS, DSC, and/or cruise control? Because those are features I’d love to keep if possible
Cruise works, yes. Just had to wire the cruise buttons to my standalone, and it controls the DBW throttle body accordingly. DSC/ABS are not functional in my build but that's because I simply couldn't fit the module anywhere in the engine bay with the LS in there. Otherwise, it would most likely work as the standalone emulates the factory ECU on the CAN BUS.
It would likely still work, but I had to remove it to clear the engine as it was in the way. Note that there isn't really a CAN BUS engine, but rather a CAN BUS ECU that happens to run said engine. Always possible to swap to a standalone if the engine is supported.
When the RX8 is on the Can bus can you read information from other components on the bus and use it as an input to the Haltech? For example can you set up a traction control profile based off of the wheel speed sensors that are an input sent to the factory ABS module?
This is a good question. It does indeed look like the Haltech supports reading the wheel speed sensors from the RX8s can bus, though I can't test this on my car as the ABS model is gone.
Your videos got me working on my project car again, i had the engine in but had no clue where to start with wirinf and tuning so it just sat there for 2 years while i did some other smaller projects. Keep it up man!
